Suillus grevillei

Ciri dan struktur

PILEUS: convex to plano-convex, 5-15 cm diam., mucilaginous, glabrous, golden brown, often paling toward margin, frequently streaked or blotched with lemon yellow or golden yellow; cuticle an ixotrichodermium, readily separable, composed of gelatinised, hair-like, septate hyphae 3.5-6 µm diam.; margin typically entire, occasionally lacerate. HYMENOPHORE: tubes to 11 mm long, adnate to subdecurrent, lemon yellow to golden yellow; pores concolorous with tubes, angular, 0.5-1 mm diam., becoming brownish where damaged. STIPE: 4.5-10 cm long, equal or tapering apically, 1-2.3 cm diam., solid, finely but distinctly reticulate above annulus, subpruinose or subglabrous below, concolorous with pores apically, yellow, golden brown or brownish below; glandulae absent: flesh pallid yellow; annulus typically conspicuous, rarely absent, superior, pallid yellow or brownish yellow. SPORES: spore print yellowish brown (between Sayal Brown and Cinnamon); spores pallid melleous, elliptic-subfusiform, (8)-8.6-10-(13.5) X 2.8-3.5-(4) µm, smooth. HYMENIUM: basidia hyaline, clavate, 17.5-25 X 4.5-6.5 µm, 4-spored; cystidia numerous, often in groups, hyaline or encrusted with brown, resinous material, subcylindrical to clavate, 30-55 X 6-9 µm. HYMENOPHORAL TRAMA: bilateral, of the Boletus subtype; clamp connections absent. CONTEXT OF PILEUS: lemon yellow, often with golden yellow areas, unchanging on exposure to air. TASTE: mild. SMELL: not distinctive. CHEMICAL REACTIONS: KOH on pileus—grey; on context of pileus—immediate red flush turning lilac; NH4OH on pileus—orange tan; on context—immediate red flush turning lilac.

Habitat dan peran ekologis

Suillus grevillei is an introduced species, which under natural conditions forms mycorrhizal associations solely with Larix. However, Young (1940) has shown that in pure culture it is capable of forming mycorrhizas with Pinus caribea and P. taeda. In New Zealand it is commonly associated with Larix decidua and has been observed under L. leptolepis (W. A. Holloway, pers. comm.). Slipp and Snell (1944) and Smith, Thiers, and Miller (1965) recorded exannulate fruitbodies of Suillus grevillei. In one of the above collections (24341), a quarter of the fruitbodies lacked an annulus, and in some there were no indications of velar remnants on the pileus margin. The species is reported to be edible, but opinions differ as to its quality. S. grevillei may be distinguished by the presence of an annulus, absence of glandulae on the stipe, and its association with Larix. Which was first recorded from New Zealand (as Boletus elegans) by Rawlings (1951).
